"You'll find out about very evident flaws. And that's about it."
I couldn't disagree more. Looking in the time domain is far more likely to reveal tricky problems than anything else remotely affordable. Yea, you need a fast stimulus but that's easy and cheap. Not to say that one SHOULDN'T measure amplitude and phase, it gives your data some Bode, as it were. But a scope is far and away the single most valuable general instrument there is for things electronic and with a cheap Fn generator and a little work will also give you both the real and imaginary parts of the transfer function.
NOW I'm not saying that using your soundcard and some software is going to do the trick. That's fine for in-band sweeps and FFT's but won't generally get you to causation. A fast scope (and the right skills) usually will.
